Gaza war humanitarian crisis: From Self-Defence to Control

Israel’s Gaza war, sparked by Hamas’s 2023 attack, has spiralled into a humanitarian crisis, displacing millions.

Israel’s war in Gaza began under the shadow of horror. Hamas’s October 7, 2023, attack massacred Israeli civilians and took hostages. Many outside Israel accepted the premise of self-defence through force. Nearly two years on, that moral and strategic consensus has collapsed.

Gaza lies in ruins, with over 60,000 Palestinians reported killed and famine conditions spreading; about 1.9 million people, nearly the entire population, have been displaced multiple times. Israel’s leadership now signals a new offensive to seize Gaza City and extend control over remaining areas, while insisting this is not “occupation” but necessary security.

The facts on the ground and the human toll tell a different story.
This blog traces how a war initially framed as just retaliation evolved into a humanitarian calamity and a political project that became increasingly untethered from its original aims.

It examines the drivers of escalation, the challenge to just-war principles, and the implications of de facto re-occupation for Palestinians, for Israel, and for a world order that claims to defend civilian immunity and the rule of law.

Losing the Strategic and Moral Grounding

Wars lose their moral footing when aims expand faster than legitimacy can carry them. Israel’s initial goals to punish perpetrators, free hostages, and degrade Hamas were legible to much of the world. But the campaign’s means quickly outgrew its ends. Indiscriminate effects, systematic devastation of civilian infrastructure, and a siege that throttled aid corroded the claim of proportional self-defence.

Strategically, destruction without a political horizon created the classic trap: every tactical success births a larger strategic failure. Hamas is weakened but not eliminated; it adapts, disperses, and reappears, while the civilian catastrophe generates new rage and legitimacy costs for Israel.

By mid-2025, independent conflict data showed Hamas retained operational capacity, contradicting triumphalist claims even as Israeli leaders prepared another push on Gaza City. Hostages remain, international pressure mounts, and the battlefield has turned into a recruitment poster. This is not a victory; it is a strategic drift.

Morally, the longer the war proceeds with mass civilian harm, the more it fails the jus in bellum tests of discrimination (protecting civilians) and proportionality (the scale of force relative to legitimate aims). These are not abstract seminar terms; they are the minimal disciplines of war recognised in ethics and law.

Why the War Continues: Politics, Military Logic, Ideology

Three forces keep the war going after Hamas’s threat has markedly diminished.

Domestic politics. Prime Minister Benjamin Netanyahu’s coalition depends on hard-right partners who equate restraint with defeat.

Politically, promising “security control” over Gaza plays to his base, postpones a reckoning over October 7 failures, and defers elections. Even in 2023–24, he signalled indefinite Israeli security responsibility for Gaza; by 2024, he published a “day after” paper envisioning open-ended military control. These are not slips; they are a program.

Military logic. Bureaucracies prosecute the war they are given. Territory becomes a metric of success; “clearing” neighbourhoods becomes a self-replicating operation. Yet even Israel’s generals have baulked at proposals for full re-occupation, warning of endless guerrilla war and risks to hostages.

Reports of civil-military rifts over the latest plan seizing Gaza City and additional zones show how political maximalism is colliding with professional caution.

Ideology. The war is increasingly narrated not as a discrete campaign against a militia but as part of a long project of control, from siege to settlement growth to the rejection of Palestinian statehood.

In that frame, humanitarian costs are regrettable but acceptable; displacement is a “temporary” necessity; and reconstruction waits upon submission. Such logic is strategically myopic and morally corrosive.

Just War Theory on Trial: Proportionality and Discrimination

Discrimination demands shielding civilians from direct attack; proportionality demands that the harm inflicted not be excessive relative to the concrete military advantage. These principles form the backbone of the just war doctrine and are codified throughout international humanitarian law. They allow war; they discipline it.

Gaza’s reality mocks these standards. Mass civilian fatalities tens of thousands identified by Gaza’s health authorities, with UN agencies regularly citing and contextualising those numbers, are not incidental. Civilian infrastructure has been severely damaged: homes, schools, hospitals, and water networks.

A World Bank/UN assessment estimated direct damage at $18.5 billion by January 2024 alone, 97% of the 2022 West Bank–Gaza GDP, with housing taking the overwhelming majority of the hit. Subsequent economic analysis reported an 83% contraction of Gaza’s GDP in 2024, near-total paralysis of daily life.

These are not the scars of a narrowly tailored campaign; they are the footprint of urban obliteration.

Worse, the siege-induced hunger aid blockages, failed deconfliction, deadly chaos around convoys and airdrops have produced starvation deaths documented in recent reporting. When a war policy predictably creates famine, the proportionality calculus breaks; whatever the initial casus belli, the means become morally indefensible.

Occupying “All of Gaza”: Consequences for Palestinians and Israel

Suppose Israel seizes Gaza City and extends control to the remaining areas.

In that case, the immediate Palestinian consequences are stark: further displacement into ever-smaller “safe zones,” deepening aid bottlenecks, and exhausted medical systems unable to absorb new waves of trauma.

The medium-term risk is a durable insurgency: the more people are dispossessed, the more a movement like Hamas (or its successor fragments) can regenerate, however degraded its current capabilities.
For Israel, the costs spread outward:

Security quagmire. Occupation without a political settlement renders tactical wins ineffective. Urban control demands a workforce and creates permanent targets. Israeli military leaders have cautioned against this trap.

International isolation. The International Court of Justice has issued provisional measures recognising a risk of genocide and ordering steps to prevent it; many states read those orders as a binding call to change course. In parallel, the International Criminal Court has issued arrest warrants for the Israeli prime minister and former defence minister for alleged war crimes and crimes against humanity, joined by warrants for Hamas leaders over the October 7 atrocities.

These moves don’t stop wars; they reshape diplomacy, travel, arms sales, and alliances.

Economics and legitimacy. Donors will not bankroll reconstruction under open-ended Israeli control. Meanwhile, allied publics and some allied governments are already curbing arms transfers and pressing for ceasefire/hostage deals, especially as famine warnings harden. The longer the campaign persists, the thinner Israel’s coalition of support becomes.

Why the “Diminished Threat” Argument Matters

If Hamas is no longer a significant military threat, the moral and legal rationale for the present scale of violence collapses. Even if one rejects that premise and insists Hamas retains dangerous capabilities, necessity still governs: force must be the least harmful means to secure legitimate aims, not a default mode of political rule.

Current reporting indicates that Hamas remains degraded but active, precisely the scenario where intelligence, targeted operations, and a political settlement including a serious hostage deal become more, not less, urgent.

The Global South’s View: Double Standards and the Politics of Law

From Nairobi to New Delhi to Brasília, the Gaza war has become a referendum on Western credibility. The same capitals that rightly demand Russian accountability in Ukraine have too often hedged, delayed, or armed through Gaza.

For many in the Global South, this is not nuance; it is a double standard. That perception accelerates a broader geopolitical realignment: if law is instrumental and civilian lives negotiable, then the old moral hegemony is spent.

International mechanisms have begun to respond to ICJ measures, ICC warrants, but law without enforcement is merely a sermon. The burden now shifts to states: comply with court orders, condition arms on humanitarian access and civilian protection, fund and secure unfettered aid corridors, and support a political process that includes Palestinian self-determination rather than postponing it indefinitely.

What a Responsible Endgame Requires

A credible exit requires seven moves:
Immediate ceasefire–hostage framework. Link a verifiable ceasefire to staged hostage releases and prisoner exchanges, monitored by third parties with teeth. (Every day of drift increases risks to both civilians and hostages.)

Humanitarian surge under protection. Open multiple land corridors with guaranteed deconfliction; protect convoys; end the starvation logic; restore water, power, and medical supply lines.

No unilateral re-occupation. End indefinite “security responsibility” plans that amount to rule without rights. Replace them with a transitional international administration focused on civil services, election preparation, and security sector reform, time-bound and accountable.

Accountability on all sides. Support the ICJ and ICC tracks; resist political interference. Accountability is not vengeance; it is the only bridge back to law when war has shredded it.

Reconstruction with conditionality. A Marshall-scale effort focused on housing, health, and education, conditioned on open borders for materials, governance reforms, and rejection of attacks on civilians. The World Bank and regional funds must lead.

Regional security compact. Deter cross-border fire, codify rules for holy sites, and create incentives that make spoilers pay whether militias or ministers.

A real political horizon. Pledges of a Palestinian state cannot remain ritual. Without a horizon, security becomes occupation by another name and the cycle restarts.

Conclusion: The Choice Is Political, Not Inevitable

Israel had a legitimate right to self-defence after October 7. It did not have a blank cheque to remake Gaza by fire. The war’s strategic dividends have dwindled; its moral costs have exploded. A campaign that once sought to defeat Hamas is now primarily defeating civilians and eroding the very norms that protect civilians everywhere.

The following offensive promises more of the same: more ruins, more displacement, more famine, and a deeper plunge into political isolation. An occupation of all Gaza, whether named as such or smuggled in as “security responsibility,” would entrench insurgency and lock Israel and Palestinians into a permanent emergency.

The alternative is more challenging because it requires courage: a ceasefire tied to the release of hostages, humanitarian restoration, international custodianship, and a binding political horizon. That, not another “decisive” operation, is the path back from catastrophe.

History will not judge intentions; it will judge outcomes. Gaza does not need more statements about safety zones or surgical strikes. It requires the end of a strategy that has turned a war of self-defence into a project of domination. The choice remains, as ever, a political one, and it can still be reversed.
